LATERAL-MOTION ROLLER-BEARING.

Specification of Letters Patent.

Patented Feb. 2, 1915,

Application filed July 13, 1914. Serial No. 850,602.

'-Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper- This invention relates to lateral motion roller bearing devices for cars and provides an improved roller cage whereby the rollers are not only spaced but are interlocked to one of the roller bearing plates or members. Generally-stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

In the accompanying drawings which illustrate the invention, like'characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a view partly in vertical section but chiefly in front elevation and with some parts broken away, showing a car bolster, a combined spring cap and roller base, interposed rollers and roller cage; Fig. 2 is a perspective view of the roller cage; Fig. 3 is a planview with some parts broken away, showing the combined spring cap and roller base, rollers and cage; and Fig. 4 is a fragmentary view in side elevation of the parts shown in Fig. 3.

The car bolster 1 may be of the usual or any suitable construction, so far as this invention is concerned. The combined spring cap and roller base 2 is supported from the truokframe by springs 3 in the customary way, and at its front and rear ends, is provided with vertical column seats in the form of large notches 4; that guide it for vertical movements on the bolster columns 5. The bolster 1 and combined spring cap and roller base are provided with the concave which engage the lateral motion rollers 6 and co'clperate therewith, in any well known Just above and inward of the column seats 4 the combined spring cap and roller base 2 is provided with raised and out-turned retaining flanges 7 that are angular or L-shaped in cross section.

The roller cage is made froma single piece of fiat sheet metal 8, preferably of rolled steel. The body portion of this plate 8 is cut away at 9 to afford roller receiving spaces, and it isprovided with inwardly and upwardly bent roller retaining flanges or lips 10 that engage the upper portions of rollers and support the plate on the rollers. The front and rear ends of the plate 8 are turned downward to stiffen the said plate, and are further provided with downwardly and inwardly bent retaining flanges 11 that are approximately L-shaped in cross section, and underlap the retaining flanges 7 of the combined spring cap and roller base, and thus hold the said members 2 and S interlocked and against vertical separation, but' free for horizontal traveling movements, one in respect to the other. The roller engaging surfaces, both on the bolster l and on the combined'spring cap and roller base 2 terminate in roller stop ribs 12; and here it may be noted that the said stops 12 limit "the travel of the rollers so that the retaining flanges 7 and 11 cannot be moved out of interlocking engagement by extreme traveling movements of the rollers. Hence, it follows that the retaining flanges 11 must be bent laterally into interlocking engagement with the retaining flanges 7 after the rollers are applied in the seats on the C0111- bined spring cap and roller base.

iVith the above described arrangement therefor, the rollers are held interlocked to the combined spring cap and roller base, so that they cannot be accidentally separated therefrom. Furthermore, this is accomplished by a roller cage that is formed from a single plate of sheet metal, which construction is not only of small cost but highly efiicientfor the purposes hadin view.

In the drawings, the upper roller bearing member is shown as integral with the bolster, but any form of upper roller bearing members arranged to partake of the endwise traveling movements of the bolster is herein treated as a roller bearing member on the bolster.

What I claim is:

A lateral motion roller bearing device for pending retaining flanges having interlock- 1&7

ing sliding engagement with the said retaining flanges on said lower bearing member. In testimony whereof I affix my signature in presence of two Witnesses.
